/// Stores an opaque object of a certain size, with very restricted operations
///
/// Note: due to `align(4)` / `align(8)` and not `packed` repr, this type may be bigger than `N` bytes
/// (which should be OK since C++ just needs to read/write those `N` bytes reliably).
///
///
/// For float/double inference, see:
/// * https://github.com/godotengine/godot-proposals/issues/892

/// We have to do a `target_pointer_width` check *after* code generation, see https://github.com/rust-lang/rust/issues/42587.
